| 1 | Is nasopharyngeal cancer really a “Cantonese cancer”?显示文摘Nasopharyngeal cancer(NPC) is endemic in Southern China,with Guandong province and Hong Kong reporting some of the highest incidences in the world.The journal Science has called it a 'Cantonese cancer'.We propose that in fact NPC is a cancer that originated in the Bai-Yue('proto-Tai-Kadai' or 'proto-Austronesian' or 'proto-Zhuang') peoples and was transmitted to the Han Chinese in southern China through intermarriage.However,the work by John Ho raised the profile of NPC,and because of the high incidence of NPC in Hong Kong and Guangzhou,NPC became known as a Cantonese cancer.We searched historical articles,articles cited in PubMed,Google,monographs,books and Internet articles relating to genetics of the peoples with high populations of NPC.The migration history of these various peoples was extensively researched,and where possible,their genetic fingerprint identified to corroborate with historical accounts.Genetic and anthropological evidence suggest there are a lot of similarities between the Bai-Yue and the aboriginal peoples of Borneo and Northeast India;between Inuit of Greenland,Austronesian Mayalo-Polynesians of Southeast Asia and Polynesians of Oceania,suggesting some common ancestry.Genetic studies also suggest the present Cantonese,Minnans and Hakkas are probably an admixture of northern Han and southern Bai-Yue.All these populations have a high incidence of NPC.Very early contact between southern Chinese and peoples of East Africa and Arabia can also account for the intermediate incidence of NPC in these regions. | Joseph Tien Seng Wee Tam Cam Ha Susan Li Er Loong Chao-Nan Qian | 2010 | Chinese Journal of Cancer2010，29，5： | 37 |
| 2 | Contents of four active components in different commercial crude drugs and preparations of Danshen (Salvia miltiorrhiza)显示文摘AIM:To detect the contents of four active components of Salvia miltiorrhiza in various commercially available danshen crude drugs and preparations.METHODS:Commercially available danshen crude drugs from different sources,as well as danshen pills and intravenous injection preparations containing danshen alone or in combination with other herbs were collected.The composition of these danshen samples was analyzed using HPLC.Specifically,the amounts of magnesium tanshinoate B(MTB),danshensu,isotanshinone IIA,and cryptotanshinone were determined.In some of these samples,the content of MTB was further confirmed by liquid chromatography-tandem mass spectrometer (LC-MS)/MS method.RESULTS:There were great variations in the amount of the four active ingredients in the commercially available danshen crude drugs and drug preparations in this study.The amount of MTB was the highest among the four components measured in the crude drugs.However,the amounts of MTB in all danshen preparations were much lower than those in crude drugs.The 2 lipophilic components,isotanshinone IIA and cryptotanshinone,were very low or not detectable in both injection and oral preparations.CONCLUSION:MTB can be used to standardize the various forms of danshen crude drugs and drug preparations from different sources.In view of the variation in the amounts of MTB and other components,improvement in the production methods of danshen preparations is essential to ensure consistent amount of its active ingredients and reproducible pharmacological actions. | Susan Wai Sum LEUNG Yaw Loong SIOW Ricky Ying Keung MAN | 2002 | Acta Pharmacologica Sinica2002，23，12： | 6 |

| 4 | High incidence of nasopharyngeal cancer: similarity for 60% of mitochondrial DNA signatures between the Bidayuhs of Borneo and the Bai-yue of Southern China显示文摘Populations in Southern China (Bai-yue) and Borneo (Bidayuh) with high incidence of nasopharyngeal cancer (NPC) share similar mitochondrial DNA signatures, supporting the hypothesis that these two populations may share the same genetic predisposition for NPC, which may have first appeared in a common ancestral reference population before the sea levels rose after the last ice age. | Joseph Wee Tam Cam Ha Susan Loong Chao-Nan Qian | 2012 | Chinese Journal of Cancer2012，31，9： | 0 |
